Lost in a dense jungle, pursued by hostile natives, a group of embattled adventurers searches for a place to make a stand. Instead, the group stumbles on the ruins of a long-lost civilizaion fraught with deadly traps, sinister puzzles and bizarre monsters. If the heroes want to survive, they must escape the dungeon without succumbing to the deadly poisonous gas or one of a hundred spells.

Hidden Shrine of Tamoachan is a Dungeons & Dragons Roleplaying Game adventure designed as a homage to the classic 1980 adventure. It includes a full-color poster map and features over fifty rooms filled with items, monsters and traps adapted from the original adventure.
